Description

Technical Field

[0001] The present invention relates to the technical field of protective cases, and in particular to a protective case for digital products. Background Art

[0002] With the advancement of technology and the emergence and development of computers, a wave of digitally recorded products has emerged, replacing traditional methods like film, videotapes, and audiotapes. These products are collectively referred to as digital products. For example, televisions, communication equipment, and mobile devices, such as smartphones and portable electronic tools like Bluetooth headsets, have all adopted digital technology to a significant degree and are collectively referred to as digital products. With the widespread adoption of digital products like smartphones and Bluetooth headsets, effective protective housings are needed to protect them from scratches and damage. However, most current protective cases are made of plastic or other soft plastic materials, resulting in relatively simple structures and poor shock absorption. This makes them particularly susceptible to damage from sideways drops and falls. To address these issues, some protective cases on the market utilize multiple layers of hard and soft plastic materials. While these offer some improved cushioning, they are bulky and require a certain thickness to provide adequate drop protection. Summary of the Invention

The shape of the section lines, including the inclination angle and spacing distance, does not strictly follow the section line settings for different materials in mechanical drawings. For example, in the drawings herein, a section line inclined at 45° does not necessarily represent a metal material, but may also represent other non-metallic materials.

[0037] In one embodiment, Figures 1 to 3As shown, the digital product protective case includes a main body 100 and an air spring assembly 200. It should be noted that the digital products mentioned here include televisions, communication equipment and mobile terminals, and mobile terminals include mobile phones, tablet computers, Bluetooth headsets, etc. The structure of the digital product protective case is as follows Figures 1 to 3 As shown, Figure 1 This is a structural diagram of the main body 100 and the air spring assembly 200 before assembly. Figure 2 Schematic diagram of the exploded structure of the air spring assembly 200. Figure 3 FIG. 1 is a longitudinal cross-sectional view of the assembly of the main body 100 and the air spring assembly 200. Figures 1 to 3 As shown, the main body 100 includes a side frame 110 and a cover 120. The side frame 110 surrounds the outer edge of the cover 120, and the side frame 110 and the cover 120 together form a receiving cavity 130 for accommodating digital products. The cover 120 includes a back cover 122. The side of the receiving cavity 130 opposite to the back cover 122 is open to facilitate the placement of digital products. Figure 2 and Figure 3 As shown, the air spring assembly 200 includes a first sheet 210 and a second sheet 220. An inner cavity 211 is formed inside the first sheet 210. The periphery of the first sheet 210 is sealedly connected to the periphery of the second sheet 220, thereby forming a closed cavity 230 between the first sheet 210 and the second sheet 220. The closed cavity 230 is filled with gas, that is, the air spring assembly 200 forms a closed airbag alone, which is elastic and can play a role in cushioning and resisting falls.

[0038] In one embodiment, the first sheet 210 and the second sheet 220 are both made of plastic material, and the first sheet 210 and the second sheet 220 are edge-fused by a pressing process. The pressing process includes a high-frequency process or an ultrasonic process, wherein high frequency means high-frequency wave. High frequency and ultrasonic wave are two different concepts. High frequency refers to electromagnetic waves with a frequency greater than 100KHz, and ultrasonic wave refers to sound waves with a frequency greater than 20 kHz. The principle of high-frequency welding is also different from that of ultrasonic wave. High frequency uses a high-frequency electromagnetic field to cause the molecules inside the material to collide violently with each other to generate high temperature to achieve the purpose of welding, while ultrasonic wave uses the principle of frictional heat generation to generate a large amount of heat to achieve the purpose of welding. In a specific embodiment, the first sheet 210 and the second sheet 220 can be edge-fused by a high-frequency process or an ultrasonic process.

[0039] like Figure 3 As shown, the air spring assembly 200 is connected to the side frame 110, and the outer surface of the air spring assembly 200 protrudes from the outer surface of the side frame 110. It should be noted that the outer surface of the side frame 110 refers to the side surface of the side frame 110 away from the accommodating cavity 130. Specifically, as Figure 1 and Figure 3As shown, a groove 140 is provided on the side of the side frame 110 away from the accommodating cavity 130, and the air spring assembly 200 is embedded in the groove 140. In a specific embodiment, the air spring assembly 200 can be embedded in the groove 140 by embedding, that is, by an in-mold injection molding process. First, the air spring assembly 200 is placed in the mold cavity for molding the side frame 110, and the second sheet 220 of the air spring assembly 200 is close to the mold cavity. Then, a high-temperature molten plastic material is injected into the mold cavity, thereby tightly combining the air spring assembly 200 and the side frame 110. In another specific embodiment, the air spring assembly 200 can also be embedded in the groove 140 by a dispensing process. Figure 3 As shown, the side of the second sheet 220 facing away from the sealed cavity 230, as well as the upper and lower ends of the first sheet 210, are bonded to the inner wall of the groove 140, allowing the air spring assembly 200 to be firmly embedded in the groove 140. It is understood that in other embodiments, the groove 140 may not be provided on the side frame 110, and the air spring assembly 200 may be directly provided on the side surface of the side frame 110 facing away from the accommodating cavity 130 through a dispensing process or an in-mold injection process. In this case, the air spring assembly 200 as a whole protrudes from the side surface of the side frame 110 facing away from the accommodating cavity 130. When a digital product falls from a height or is impacted by external force, the air spring assembly 200 can act as a buffer, dispersing and absorbing the impact force during the fall, and effectively protecting the digital product from damage.

[0040] In addition, considering that the edges and corners of digital products are easily bumped during use, Figure 3 In the illustrated embodiment, the side frame 110 and the back cover 122 of the main body 100 are made of different materials. Specifically, the side frame 110 is made of TPU soft rubber material to increase the impact resistance and cushioning capabilities of the corners of the protective shell; the back cover 122 is made of a transparent hard plastic material, for example, PC plastic with good transparency and mechanical properties. In addition, in order to improve the bonding strength between the different materials of the side frame 110 and the back cover 122, the main body 100 can adopt an in-mold injection molding method, that is, first injection molding the back cover 122, and then the molded back cover 122 and the air spring assembly 200 are placed in the molding mold of the side frame 110, and the side frame 110 is molded on the outer edge of the back cover 122.

[0041] In addition, if Figure 1As shown, the protective shell is rectangular, and the corners of the side frame 110 are transitioned through arcs. The side frame 110 includes a side portion 111 and an arc portion 112 connected in sequence. In the process of using digital products, the corners are generally easy to be bumped. The groove 140 is set on the arc portion 112, and the air spring assembly 200 is embedded in the groove 140 of the arc portion 112, thereby improving the buffering capacity of the corners of the protective shell and effectively protecting the digital product from being damaged. It is understandable that in other embodiments, such as Figure 4 As shown, the groove 140 can also be provided on the side portion 111 and the arc portion 112 at the same time, and the air spring assembly 200 is embedded in the groove 140 of the side portion 111 and the arc portion 112. The digital product is provided in the accommodating cavity 130 in the main body 100. When the digital product falls from a height or is impacted by an external force, the air spring assembly 200 can better play a buffering role, disperse and absorb the impact force during the fall, and more effectively protect the digital product from being damaged. In addition, it should be noted that in other embodiments, the side frame 110 of the protective shell can also be in an arc shape as a whole. In this case, it is necessary to open a groove 140 around the entire circumference of the side frame 110, and the air spring assembly 200 is embedded in the groove 140 to improve the impact resistance of the protective shell.

[0042] In addition, if Figure 4 As shown, there are two or more grooves 140, which are spaced apart on the side of the side frame 110 away from the accommodating cavity 130 and arranged along the circumference of the side frame 110. The number of air spring assemblies 200 is the same as the number of grooves 140. The air spring assemblies 200 are embedded in the grooves 140 in a segmented manner. Functional areas 600 are provided between different grooves 140 on the side frame 110. Functional holes or buttons can be provided on the functional areas 600. The functional holes are used to insert power cords, data cables, or headphone plugs, or to transmit signals or sounds, or to connect lanyards, etc. It is understandable that when the functional areas 600 are not provided on the side frame 110 of the protective case, the grooves 140 can be continuously provided on the side of the side frame 110 away from the accommodating cavity 130. In this case, the first sheet 210 and the second sheet 220 of the air spring assembly 200 are both integrally formed structures, and the air spring assembly 200 is continuously embedded in the grooves 140.

[0043] It should be noted that in Figure 1 、 Figure 3 and Figure 4 In the embodiment shown, a groove 140 is formed on the side of the side frame 110 away from the accommodating cavity 130, and the air spring assembly 200 is embedded in the groove 140. It is understood that in other embodiments, such as Figure 5As shown, a through hole 150 may be provided on the side frame 110, and the air spring assembly 200 may be embedded in the through hole 150. It is understood that the groove 140 and the through hole 150 provided in the side frame 110 may be collectively referred to as an installation position, and the air spring assembly 200 may be embedded in the installation position of the side frame 110 to improve the cushioning performance of the protective shell. In a specific embodiment, as shown in FIG. Figure 5 As shown, the air spring assembly 200 can be embedded in the through hole 150 of the side frame 110 by a dispensing process or an in-mold injection process. Figure 5 As shown, the volume of the enclosed cavity 230 within the air spring assembly 200 can be increased, thereby improving the elasticity of the air spring assembly 200 and further enhancing the cushioning performance of the protective case. It is understood that when the air spring assembly 200 is embedded in the through hole 150 of the side frame 110, if the volume of the enclosed cavity 230 within the air spring assembly 200 does not increase, the height of the air spring assembly 200 protruding from the outer surface of the side frame 110 can be appropriately reduced, thereby reducing the volume of the protective case and improving its portability.

[0044] In another embodiment, Figure 6 As shown, when the air spring assembly 200 is embedded in the through hole 150 of the side frame 110, by increasing the thickness of the side frame 110, the outer surface of the air spring assembly 200 can be made flush with or smoothly transitioned to the outer surface of the side frame 110, thereby making the surface of the side frame 110 of the protective shell rounded and smooth, improving the aesthetics. It is understood that in other embodiments, when the air spring assembly 200 is embedded in the through hole 150 of the side frame 110, the volume of the enclosed cavity 230 within the air spring assembly 200 can also be reduced to make the outer surface of the air spring assembly 200 flush with or smoothly transition to the outer surface of the side frame 110.

[0045] In yet another embodiment, Figures 7 to 9As shown, the cover 120 includes a front cover 121 and a rear cover 122 disposed opposite each other, with the side frame 110 disposed between the front cover 121 and the rear cover 122. A closable opening 170 is provided on the main body 100 to facilitate the insertion of digital products. The main body 100 includes a first split body 161 and a second split body 162 that are detachably connected, with the closable opening 170 formed between the first split body 161 and the second split body 162. A recess 140 is defined on the side of the side frame 110 facing away from the accommodating chamber 130. Recess 140 includes a first recess 141, a second recess 142, and a third recess 143. First recess 141 is defined on the side of the first split body 161 facing away from the accommodating chamber 130. Second recess 142 and third recess 143 are defined, spaced apart, on the side of the second split body 162 facing away from the accommodating chamber 130. A functional area 600 is defined between the second recess 142 and the third recess 143. Functional area 600 may include function holes or buttons for inserting power cords, data cables, or headphone plugs, transmitting signals or sound, or connecting a lanyard. The air spring assembly 200 includes a first component 240, a second component 250, and a third component 260. First component 240 is embedded in first recess 141; second component 250 is embedded in second recess 142; and third component 260 is embedded in third recess 143.

[0046] In addition, it should be noted that Figures 7 to 9 In the embodiment shown, the number of the air spring assemblies 200 is the same as the number of the grooves 140 on the side frame 110, and the shape of the air spring assemblies 200 matches the shape of the grooves 140 on the side frame 110, so that the air spring assemblies 200 can be embedded in the grooves 140 of the side frame 110. Figure 7-Figure 8 As shown, the air spring assembly 200 comprises a first sheet 210 and a second sheet 220. The first sheet 210 is formed with an inner cavity 211. The periphery of the first sheet 210 is sealed to the periphery of the second sheet 220, thereby forming a closed cavity 230 between the first sheet 210 and the second sheet 220. The closed cavity 230 is filled with gas, that is, the air spring assembly 200 forms a closed airbag alone, which is elastic and can play a role in cushioning and resisting falls. The molding process of the air spring assembly 200 and the connection process of the air spring assembly 200 and the main body 100 are similar to the above-mentioned process. Figures 1 to 6 The embodiments shown are the same and will not be described again here.

[0047] In addition, in yet another embodiment, Figure 10 and Figure 11As shown, through holes 150 may also be provided on the side frame 110. The through holes 150 include a first through hole 151, a second through hole 152, and a third through hole 153. The first through hole 151 is provided on the first sub-body 161, and the second through hole 152 and the third through hole 153 are provided on the second sub-body 162 at intervals. A functional area 600 is provided between the second through hole 152 and the third through hole 153. The air spring assembly 200 includes a first component 240, a second component 250, and a third component 260. The first component 240 is embedded in the first through hole 151; the second component 250 is embedded in the first through hole 152; and the third component 260 is embedded in the third through hole 153.

[0048] and Figure 5 Similar to the embodiment shown, Figure 10 and Figure 11 In the illustrated embodiment, by embedding the air spring assembly 200 within the through-hole 150 of the side frame 110, the volume of the enclosed cavity 230 within the air spring assembly 200 can be increased, thereby improving the elasticity of the air spring assembly 200 and further enhancing the cushioning performance of the protective case. It will be appreciated that when the air spring assembly 200 is embedded within the through-hole 150 of the side frame 110, if the volume of the enclosed cavity 230 within the air spring assembly 200 does not increase, the height of the air spring assembly 200 protruding from the outer surface of the side frame 110 can be appropriately reduced, thereby reducing the volume of the protective case and improving its portability.

[0049] In another embodiment, Figure 12 As shown, when the air spring assembly 200 is embedded in the through hole 150 of the side frame 110, by increasing the thickness of the side frame 110, the outer surface of the air spring assembly 200 can be made flush with or smoothly transitioned to the outer surface of the side frame 110, thereby making the surface of the side frame 110 of the protective shell rounded and smooth, improving the aesthetics. It is understood that in other embodiments, when the air spring assembly 200 is embedded in the through hole 150 of the side frame 110, the volume of the enclosed cavity 230 within the air spring assembly 200 can also be reduced to make the outer surface of the air spring assembly 200 flush with or smoothly transition to the outer surface of the side frame 110.

[0050] Specifically, in Figures 7 to 12 In the embodiment shown, the digital product 500 is a Bluetooth headset charging box, which is provided with a headset receiving cavity (not shown in the figure) and a headset charging position (not shown in the figure). Figure 9 、 Figure 11 and Figure 12In the illustrated embodiment, the side frame 110 of the main body 100 and the front cover 121 and back cover 122 are integrally formed using the same material. The main body 100 can be made of soft rubber materials such as TPU and TPE to provide shock absorption and drop resistance, effectively dispersing and absorbing the impact of a drop of a digital product, thereby preventing the digital product from being damaged. It is understood that in other embodiments, only the side frame 110 of the main body 100 can be made of soft rubber materials such as TPU and TPE to increase the impact resistance and cushioning capabilities of the corners of the protective case, and the front cover 121 and back cover 122 of the main body 100 can be made of other materials, such as PC materials with good transparency.

[0051] The digital product protective case of the present invention, by reasonably setting the structure of the air spring assembly 200 and the connection relationship between the air spring assembly 200 and the main body 100, the periphery of the first sheet 210 of the air spring assembly 200 is sealed with the periphery of the second sheet 220, and a closed cavity 230 is formed between the first sheet 210 and the second sheet 220.
